说明:

transition 属性是一个简写属性,用于设置四个过渡属性:

  • transition-property
  • transition-duration
  • transition-timing-function
  • transition-delay
描述
默认值: all 0 ease 0
JavaScript 语法: object.style.transition="width 2s"

语法

transition: property duration timing-function delay;
描述
transition-property 规定设置过渡效果的 CSS 属性的名称。 如:transition-property:width;
transition-duration 规定完成过渡效果需要多少秒或毫秒。如:transition-duration: 5s;
transition-timing-function 规定速度效果的速度曲线。如:transition-timing-function: linear;
transition-delay 定义过渡效果何时开始。如: transition-delay: 2s; 在过渡效果开始前等待 2 秒:

transition-timing-function 速度曲线属性说明

定义和用法

transition-timing-function 属性规定过渡效果的速度曲线。

该属性允许过渡效果随着时间来改变其速度。

描述
默认值: ease
JavaScript 语法: object.style.transitionTimingFunction="linear"

语法

transition-timing-function: linear|ease|ease-in|ease-out|ease-in-out|cubic-
bezier(n,n,n,n);
描述
linear 规定以相同速度开始至结束的过渡效果(等于 cubic-bezier(0,0,1,1))。
ease 规定慢速开始,然后变快,然后慢速结束的过渡效果(cubic-bezier(0.25,0.1,0.25,1))。
ease-in 规定以慢速开始的过渡效果(等于 cubic-bezier(0.42,0,1,1))。
ease-out 规定以慢速结束的过渡效果(等于 cubic-bezier(0,0,0.58,1))。
ease-in-out 规定以慢速开始和结束的过渡效果(等于 cubic-bezier(0.42,0,0.58,1))。
cubic-bezier(n,n,n,n) 在 cubic-bezier 函数中定义自己的值。可能的值是 0 至 1 之间的数值。

提示:请在实例中测试不同的值,这样可以更好地理解它们的工作原理。

要加前缀

animation @keyframes

CSS3 @keyframes 规则

如需在 CSS3 中创建动画,您需要学习 @keyframes 规则。

@keyframes 规则用于创建动画。在 @keyframes 中规定某项 CSS 样式,就能创建由当前样式逐渐改为新样式的动画效果。

目前浏览器都不支持 @keyframes 规则。

Firefox 支持替代的 @-moz-keyframes 规则。

Opera 支持替代的 @-o-keyframes 规则。

Safari 和 Chrome 支持替代的 @-webkit-keyframes 规则。

定义和用法

通过 @keyframes 规则,您能够创建动画。

创建动画的原理是,将一套 CSS 样式逐渐变化为另一套样式。

在动画过程中,您能够多次改变这套 CSS 样式。

以百分比来规定改变发生的时间,或者通过关键词 fromto,等价于 0%100%

0% 是动画的开始时间,100% 动画的结束时间。

为了获得最佳的浏览器支持,您应该始终定义 0%100% 选择器。

注释:请使用动画属性来控制动画的外观,同时将动画与选择器绑定。

语法

@keyframes animationname {keyframes-selector {css-styles;}}
描述
animationname 必需。定义动画的名称。
keyframes-selector 必需。动画时长的百分比。
合法的值:
0-100%
from(与 0% 相同)
to(与 100% 相同)
css-styles 必需。一个或多个合法的 CSS 样式属性。

当您在 @keyframes 中创建动画时,请把它捆绑到某个选择器,否则不会产生动画效果。

通过规定至少以下两项 CSS3 动画属性,即可将动画绑定到选择器:

  • 规定动画的名称

  • 规定动画的时长

animation

Internet Explorer 10、Firefox 以及 Opera 支持 animation 属性。

Safari 和 Chrome 支持替代的 -webkit-animation 属性。

注释:Internet Explorer 9 以及更早的版本不支持 animation 属性。

实例

div{
	animation:mymove 5s infinite;
	-webkit-animation:mymove 5s infinite; /* Safari 和 Chrome */
}

定义和用法

animation 属性是一个简写属性,用于设置六个动画属性:

  • animation-name
  • animation-duration
  • animation-timing-function
  • animation-delay
  • animation-iteration-count
  • animation-direction

注释:请始终规定 animation-duration 属性,否则时长为 0,就不会播放动画了。

内容
默认值: none 0 ease 0 1 normal
继承性: no
版本: CSS3
JavaScript 语法: object.style.animation="mymove 5s infinite"

语法:

animation: name duration timing-function delay iteration-count direction;
内容
animation-name 规定需要绑定到选择器的 keyframe 名称。。
animation-duration 规定完成动画所花费的时间,以秒或毫秒计。
animation-timing-function 规定动画的速度曲线。
animation-delay 规定在动画开始之前的延迟。
animation-iteration-count 规定动画应该播放的次数。
animation-direction 规定是否应该轮流反向播放动画。
